Relationship between endemic diseases and trace elements in the natural environment of Jilin province of China
Jilin province is in the middle of the north eastern region of China. Several endemic diseases are recognized there: endemic goiter, endemic fluorosis, Kaschin - Beck disease and Keshan disease. Their etiology is uncertain but they are widely distributed in rural areas which are not contaminated by industrial waste. This study shows that there is a regular distribution of some trace elements (Se, Mo, I, F) in soil, crops and drinking water as the natural environmental factors (topography, climate, types of soil and plant) vary from east to west in the province. Endemic goiter is widely spread in the upland areas, which are deficient in iodine. Iodine levels in the drinking water were less than 5.0 ug/l which accounted for 60.72% of total samples. Endemic fluorosis was distributed only in the lowland areas of the plains. Fluorine contents in 80% of water samples were more than 2.1 mg/1 in the disease areas. Kaschin-Bec, disease and Keshan disease were distributed in the mountains and hills of the eastern part of the province. The selenium and molybdenum contents of soils, crops and drinking water in the disease areas were lower than those of non-disease areas. The difference between them was significant (p < 0.01). Kaschin-Beck disease also occurred in the local plains where there were selenium deficiencies in crops and drinking water. The relationship between Kaschin-Beck disease and selenium in grains (corn) presented a significant correlation Keshan disease is also associated with deficiency in selenium and molybdenum. 13 references, 2 figures, 6 tables.
